To all whom t may concern:

Be it known that I, CHARLES a citizen of the United States, residing atCozad, in the county of Dawson and State of Nebraska, have inventedcertain new and useful Improvements in Cutting Apparatus forHarvesting-Machines, of which the following is a specification.

My invention relates to the cutting apparatus of mowers, binders andother harvesting machines, and the object of my invention is to provideimproved means for giving to the sickle-bar a steady movement during itsreciprocations.

In carrying out my invention I provide a bracket, of improvedconstruction, which is adapted to be secured to the finger bar by two ofthe bolts which attach the guard fingers to the bar, and to this bracketI attach a spring which engages a projection from the knives or cutters.The arrangement is such that as the sickle-bar reciprocates the springproduces a tension that insures a steady movement and prevents shocksand undesirable vibrations.

In the accompanying drawings: Figure 1 is a plan view of part of thecutting mechanism of a mowing machine with my improvements applied. Fig.2 shows a transverse section on the line 2-2 of Fig. 1. Fig, 3 is a viewillustrating the different parts of my invention. Fig. 4: is aperspective view of one of the guard fingers.

The cutting apparatus shown is of wellknown construction. My inventionmay be applied to cutters of various kinds.

The finger-bar A carries guard fingers B which are secured thereto bybolts C in the usual way. The knives or cutters E are supported andconnected in any suitable way. The knives are connected with the pitmanF by a head Gr. All of these parts are of well-known construction.

H indicates a bracket which is substan tially V-shaped. Its oppositeends are formed with eyes 72, which receive two of the bolts C whichattach the guard fingers to the finger-bar. At its opposite end thebracket carries a bolt 1, carrying a sleeve I, on which are arranged theconvolutions of a spring J, and which is threaded to receive a nut K tohold the spring in place. The spring has projecting from its lower coilan arm j which engages between the arms of the bracket H and preventsthe lower coil of the spring from turning when the knives arereciprocated. The opposite end of the spring is formed with a loop orhook j which engages a projection from the sickle-bar. Preferably Iemploy a bar L which is bolted or riveted tothe sickle-bar and hasaraised portion Z which overlaps the inner end of the cutter-head G. Thebar L carries a pin Z and this in turn carries a sleeve M with which thehooked end of the spring J engages. 7

As the cutters are reciprocated the spring J is put under tension andthe movement of the .cutters is effected against the force of thespring. In this way the cutters are given a steady movement and shocksand vibrations which might be otherwise caused are avoided. The cuttersare reciprocated in the usual way. In Fig. 1 they are shown in anintermediate position with the spring only slightly under tension, butwhenever the cutters are moved in either direction the spring is placedunder tension and exertsv a force on the cutters which tends to restrainthe reciprocation slightly and this prevents the cutters from vibratingIt will be observed that no modification of the cutting mechanism isrequired in order to apply my improvements. Two of the usual bolts Gemployed for attaching the guard fingers to the finger-bar are employedfor attaching the bracket H to said bar, and p the bar L carrying thepin Z can very easily be attached to the sickle-bar without modificationthereof.

I claim as: my 1nvention:-

1. The combination of the finger-bar, the I guard fingers boltedthereto, the cutters, a

V-shapedbracket secured to the finger-bar by two of the bolts whichattach the guard fingers thereto, a pin projecting upwardly from thecutters and a spring having a coiled portion with a vertical aXis andthe lower end of which is held against turning on the outer end of thebracket and which has also a hooked portion at its front end engagingthe pin'on the cutters.

2. The combination with the finger-bar, of the guard fingers boltedthereto, a V- shaped bracket secured to the finger-bar by two of thebolts which attach the guard fingers thereto, the cutters, a pinprojecting upwardly from the cutters, a pin projecting upwardly from therear end of the V-shaped bracket, and a spring coiled around saidvertical pin on the bracket having itsinner end held against turning andhaving a hookedpcrfim engaging the pin on the I the "bolts which andhaving a raised carriedthereby and a spring having a coiled cutters. c v

3.7 The combination of the'finger-bar, the guard fingers bolted thereto,the cutters, the cutter head attached thereto, a V-shaped bracketsecured tothe finger bar by two of attach the guard v fingers a bar (L)secured to thecutters portion which overlaps the inner end of the cutterhead, a pin projecting upwardly from the bar L, a sleeve thereto,

portion with a vertical axis attached to the bracket and the lower coilof which is held from turning when the cutters are recipro- 1b cated andwhich spring has also a hooked portion engaging the sleeve carried bythe bar L.

In testimony whereof, I have hereunto subscribed my name.
